Event ID List - What is the Syntax?

I cannot seem to find the documentation for the Syntax for the Event ID list when creating an Alert for an event in the Windows Log.
Are the event ID’s separated by a space, comma, semicolon, something else?
7 11 32

Thank you in advance.

Sorry I’m a little late to the party. We’ve had success by separating each ID with a comma and a space
